thorpej ee325b474f Back-port "spec functions" from GCC 3.3. Use if "if-exists()" spec 
function to include crti.o/crtn.o in the STARTFILE and ENDFILE
specs, respectively.

Corresponding GCC ChangeLog entry:

2002-11-19  Jason Thorpe  <thorpej@wasabisystems.com>

        * gcc.c (The Specs Language): Document spec functions.
        (static_spec_functions, lookup_spec_function)
        (eval_spec_function, handle_spec_function)
        (if_exists_spec_function, alloc_args): New.
        (execute): Abort if processing_spec_function is true.
        (do_spec_1): Hand off spec to handle_spec_function if %:
        is encountered.  If processing_spec_function is true,
        end any pending argument when the end of the string is reached.
        (main): Use alloc_args to allocate the initial argument vector.
        * gcc.h (struct spec_function): New.
        (lang_specific_spec_functions): New extern.

        * config/netbsd-elf.h (STARTFILE_SPEC): Add if-exists(crti%O%s).
        (ENDFILE_SPEC): Add if-exists(crtn%O%s).
        * config/alpha/netbsd.h (ENDFILE_SPEC): Likewise.

Organization of Sources:

This directory hierarchy is using a new organization that
separates the GNU sources from the BSD-style infrastructure
used to build the GNU sources.  The GNU sources are kept in
the standard GNU source tree layout under:

	dist/*

The build infrastructure uses the normal BSD way under:

	lib/*
	usr.bin/*

The makefiles in the above hierarchy will "reach over" into
the GNU sources (src/gnu/dist) for everything they need.


Maintenance Strategy:

The sources under src/gnu/dist are generally a combination of
some published distribution plus changes that we submit to the
maintainers and that are not yet published by them.  There are
a few files that are never expected to be submitted to the FSF,
(i.e. BSD-style makefiles and such) and those generally should
stay in src/gnu/lib or src/gnu/usr.bin (the BSD build areas).

Make sure all changes made to the GNU sources are submitted to
the appropriate maintainer, but only after coordinating with the
NetBSD maintainers by sending your proposed submission to the
<tech-toolchain@netbsd.org> mailing list.  Only send the changes
to the third-party maintainers after consensus has been reached.
